Hi everybody,
I am starting a fMRI project to help diagnosing dyslexia in children. I have
read the literature regarding the disadvantages of using adult templates in
the normalization of pediatric data, and I'm trying to use CCHMC's pediatric
templates with SPM8.
However, I am not sure of how should I install these templates on the spm8
folder, or if it does actually work for the SPM8 version. I have tried to
replace the apriori folder contents with the pediatric ones, but still the
segmentation results are not correct. I can process 1-st level analysis
skipping the segmentation and normalization steps, and showing the results
overlaying the activation map over the T1 images, but I think I need these
steps if I want to make comparisons with a control group.
How could I use CCHMC(or another) template to process pediatric functional
data in SPM8?
-I have another beginner's question in reference to the FWE threshold:
Is the 0.05 value the commonly used, or can I change its value to discover
truly activated areas not shown with it, knowing that the possiblity of a
false positive increases by doing so?
Thank you very much for all your posts and help, it's really nice to learn
reading the list:)
Best wishes,
Álvaro
